I bought the hype about how great TTI headers are… big mistake! I should have just bought another set of Tubular Automotive brand for my A motor / A body. Having to take the front suspension apart to remove the headers when the motor comes out stinks, they fit real close to the trans, I had to modify my shifter mounting bracket on the trans to clear the headers. They might be okay for a street car but a race car that the motor comes out of once in awhile they aren`t too great. The only thing I gained was not having to use a 90 degree oil filter adapter. My car sits in a dry trailer or garage and got caught in rain maybe twice and the TTIs are rusting already after 3 years. My application is a 68 Dart with a small block with Indy 360-1 heads and a 904 the TTIs are pretty much one piece also a pain when taking in and out. For $1000 I expected better fitment, ease of installation and quality… I didn't get it with TTIs .. the next time my motor comes out the TTIs aren't going back in !
